This essay focuses on the Public Art Map of Porto, published in July 2017. This printed map distributed for free by its promoter, the Porto City Council, brings together a significant set of sculptures, monuments, panels, and murals installed since the 19^th century. Given that mapping any dimension of reality is often a challenge, what portions of the city of Porto do we see represented here? What value systems does this map seek to organise? This reflection problematizes the reduced participation of women artists in the Porto’s public art scene and hopes to contribute to a questioning of the presumed neutrality of this type of documents.
